This research tested a conceptual model for proximity of clothing to self (PCS) in relation to age identity, self‐actualization, psychological well‐being, self‐assessed health, sex and chronological age among older adults, aged 65 and over, within the human ecological perspective. A mail survey was sent to a national random sample of 1700 older adults in the US resulting in 195 usable respondents in the final sample. The respondents returned two completed questionnaires, which were (1) Clothing: A Resource for Successful Aging? (to measure PCS, age identity and demographic variables) and (2) Personal Orientation Inventory (to measure self‐actualization). The results indicated that older adults' psychological well‐being, one component of successful ageing, was directly affected by their self‐assessed health, age identity and self‐actualization. PCS indirectly influenced individuals' psychological well‐being in a slightly negative way in later life. In sum, clothing may be used as a needs satisfier for different levels of needs or related more closely with needs in addition to self‐actualization needs for older adults. Further research should be conducted to explore relationships among PCS, different levels of human needs, clothing‐related variables and psychological well‐being for this age group. In practice, the effort should be given to teach the use of clothing (or other human‐built objects) as a tool or need satisfier to contribute to success in a person's later life by offering some educational or training programmes through local senior community centres or universities. 相似文献

We model competition between content distributors (platforms) for content providers, and show that whether or not content is exclusive or “multihomes” depends crucially on whether or not content providers maintain control over their own pricing to consumers: if content providers sell their content outright and relinquish control, they will tend to be exclusive; on the other hand, if content providers maintain control and only “affiliate” with platforms, then multihoming is sustainable in equilibrium. We show that the outcome under affiliation depends on the tradeoff between platform rent extraction (which increases in exclusivity) and content rent extraction (which increases in multihoming), and demonstrate that the propensity for exclusivity can be increasing, decreasing, or even nonmonotonic in content quality. Finally, if a content provider internalizes the effect of its own price on platform demand, we prove that a platform that already has exclusive access to content may prefer to relinquish control over content pricing to the content provider in order to reduce price competition at the platform level. 相似文献

The seasonal patterns observed on Monday stock returns are still unexplained by different asset pricing models. We attempt
to fill this gap in the finance literature by using the Fama-French (Journal of Financial Economics 33:3–56, 1993) risk factors to explain the Monday seasonal. The results in the study show that Monday returns are explained by risk factors
such as the market return, the size of the firms, and the book-to-market ratios of firms. 相似文献

Franchising has attracted the attention of retailing and entrepreneurship scholars in the past three decades, but evidence pertaining to how franchising affects financial performance is mixed and inconclusive. Thus, the question remains as to whether franchising firms exhibit better financial performance than non-franchising firms in the same industry. In order to find an answer to this question, our study compares the risk-adjusted financial performance of franchising versus non-franchising restaurant firms over the 1995–2008 interval, using five different performance measures: the Sharpe Ratio, the Treynor Ratio, the Jensen Index, the Sortino Ratio, and the Upside Potential Ratio. For each measure, the results revealed that franchising restaurant firms outperformed their non-franchising counterparts. Thus, we provide very robust evidence that franchising is superior on average in the restaurant industry, which can help explain the increasing popularity of franchising as a business form. 相似文献
